Cookies, visits and local storage
Your run notes, comparisons and mini-game progress can be stored in this browser. They are not an account or a cloud save. Export important notes before clearing browser data.
A shared notebook link includes your notes after the # character. Anyone receiving the link can read them; avoid private information. This site does not upload those notes as analytics.
Automatic basic counting
Cloudflare Web Analytics automatically measures visits, page views and loading performance without analytics cookies or persistent visitor identifiers. It cannot identify the same person across visits. Google Analytics loads automatically with analytics and advertising storage denied by default; before an applicable Cookie choice permits storage, it can send cookieless measurement pings. These are not a complete count of unique people. Browser privacy signals, blockers and early exits can prevent measurement.
Advertising and external sites
Google AdSense code is included for verification and advertising services. Google may process ordinary request information and, subject to applicable choices, use cookies for advertising, measurement and fraud prevention. The original game, linked videos and other websites have their own privacy practices. The hosting provider may process operational logs. Contact: zhikui@zohomail.com.
